Revoking Google's enterprise certificate comes one day after Apple did the same to Facebook. Both companies misused their developer certification, which is supposed to be for internal-only apps for employees, to make consumer-accessible ones that collected user data. That's a no-no, according to Apple's rules.

But it wasn't specifically the user data collection that sparked Apple's ire. Instead, it was using the certification – which should only be used to create employee apps – to quietly make a consumer-accessible app, which circumvents Apple's standard review process.

Google voluntarily shuttered its own app in question, Screenwise Meter, yesterday after press attention and publicly apologized. Like Facebook’s app, Screenwise monitored how folks used their iPhones.

And while it seems like Google’s app had less access than Facebook’s, it still broke Apple’s policy regarding its enterprise certificate: “Any developer using their enterprise certificates to distribute apps to consumers will have their certificates revoked.”

Apple’s move today to revoke Google’s certificate has blocked its use of early versions of Google Maps, Hangouts, Gmail and other pre-release beta apps, according to The Verge.

A serious, but likely temporary block

Considering how important testing apps is to both Facebook and now Google, it’s likely the companies are rushing to fix their strained relationship with Apple – not to mention access to their iOS testing systems.

Google is already in talks with Apple, notes Bloomberg’s Sarah Frier, and iMore's Rene Ritchie confirms that Apple is in talks with Google.

Facebook seems to have already negotiated to restore their certificate and reactivate their internal app library.
